Why some people bounce back faster from leg workouts
Human alpha-actinin-3 genotype association with exercise-induced muscle damage and the repeated-bout effect.

Surprising Findings
The ACTN3 genotype affected initial muscle damage and recovery speed, but did NOT influence the repeated-bout effect — meaning adaptation was identical regardless of gene version.
Most assume genetic advantages in recovery would also mean faster adaptation — but here, the body’s ability to adapt to repeated stress was the same for both groups.
Practical Takeaways
If you recover slowly from plyometric workouts, consider spacing them further apart — you might have the RR genotype.

When you do the same weight workout more than once, your muscles get better at handling it — so next time, you’re less sore and damaged.
People with a specific version of the ACTN3 gene (the R version) tend to get much more muscle sore and weak after jumping exercises and take longer to bounce back than people with the other version (the X version), like their muscles just can’t handle the stress as well.
Whether you have the 'speed gene' (RR) or not (XX), your muscles recover and stop getting as sore after doing jump training twice — your genes don’t change how well you bounce back.
People with a certain version of the ACTN3 gene bounce back faster after intense workouts that strain muscles, like downhill running, so they might be able to train more often without getting as sore.
